As mentioned elsewhere, a signature of enigma ciphertext is that a letter can never encode as itself.

This gives you some crude form of error checking.

The rest of it as you mentioned makes it difficult to determine, data mining the possible results for common abbreviations from other plaintext could narrow.It down.

That doesn't help at all because every key you try will lead to a candidate plaintext with no letters in common with the ciphertext.
